Embodiment
[0033] This example adopts the combined method of residual oil hydrotreating and catalytic cracking provided by the present invention, and the hydrotreated liquid phase product fractionates light components and heavy components, and the cut point is 350°C, wherein the light components are directly promoted by catalytic cracking The first-stage feed inlet at the bottom of the tube enters the reactor and contacts with the high-temperature regenerated catalyst. The heavy component is used as the second-stage feed of the riser, and enters the catalytic cracking riser reactor from the second-stage feed inlet; the second-stage feed inlet Above the first-stage feed, the height from the first feed port accounts for 1 / 10 of the total height of the riser; the catalytic cracking reaction effluent is separated into dry gas, liquefied gas, and gasoline fractions, and the fraction above diesel oil is no longer separated. After filtration, it is recycled to the residual oil hydrogenation unit...
